Abstract: The present invention provides a proton-exchange membrane fuel cell power generating equipment that keeps temperature of coolant of a fuel cell in a predetermined temperature range without stop operation of the equipment even when a hot water reserving tank is filled with hot water and the hot water is not discharged to the outside, automatically prevents freezing of a water system during stop operation of the equipment, minimizes maintenance work in a cold region or in the winter season, has high reliability with equipment's service life extended, and supplies hot water heated by efficiently recovering exhaust heat from plural heat exchangers installed in the equipment to the hot water reserving tank. The power generating equipment has a line for circulating and feeding hot water A produced by exchanging heat in the heat exchanger connected to a process gas burner for burning hydrogen until the equipment becomes stable in starting operation. When a water temperature of a water tank becomes a predetermined temperature or more, a fan for feeding air for combustion to the said process gas burner is operated to decrease temperature of the hot water A using the heat exchanger as a cooler of the hot water A and the cooled hot water A is circulated and fed to the line for cooling. The equipment has a control system that, when the water system may freeze during stop operation of the power generating equipment, prevents the freezing by detecting freezing, operating the process gas burner to circulate the hot water of the hot water reserving tank in a part or the whole of the water system. City water supplied to the bottom of the hot water reserving tank is taken out and fed to the fourth heat exchanger through the first duct, from the fourth heat exchanger to the third heat exchanger through the second duct, to the first heat exchanger through the third duct, and then to the second heat exchanger through the fourth duct, and hot water is supplied from the second heat exchanger to the upper part of the hot water reserving tank through the fifth duct via die first selector valve. The fifth duct is branched, the hot water from the second heat exchanger is guided to the water tank through the sixth duct via the second selector valve, merged with the fifth duct through the seventh duct, and returned to the hot water reserving tank. <IMAGE>

Title: Copy protection system
IPC: G11B7/007
Filed: 2001-04-27
Abstract: The invention relates to an apparatus for reading out information from an information carrier, the information including at least a first signal of at least partly encrypted content, to an apparatus for storing such information as well as to corresponding methods. The invention proposes a realisation of the Content Scrambling System (CSS) rule: CSS encrypted content on a recordable disc should be refused. In order to be able to use a wobbled disc for distinguishing ROM-discs from recordable discs, it is required that in the content on "new" discs there will be a "wobble-trigger". This trigger has the following requirements: -it should be easily detectable from looking just at the content, -it should not be easily removable by a hacker, -it should not affect content preparation. It is thus proposed according to the invention that an apparatus for reading out information comprises: means for detecting a second signal logically embedded in the first signal, means for detecting a physical mark used for storing at least part of the information on the information carrier, and means for refusing play back of the information read from the information carrier if a second signal but no physical mark has been detected.
